HowTo: Mutiple Radio Button Values

Hi - I'm a TOTAL php NEWBIE - my 1st bit of code!!!. Basically the input form page has 17 sets of radio buttons, each representing one game with 2 options - team 1 and team 2. What I want to do is a better way of checking each radio button value instead of using an if statement for each. This code doesn't really work - it finds that vars ALWAYS exist. IE: <INPUT NAME=Game1 VALUE=1>Chicago <INPUT NAME=Game1 VALUE=2>whatever <INPUT NAME=Game2 VALUE=3>Minny <INPUT NAME=Game2 VALUE=1>Nobody Code above is processed by the following code: for ($GameIdx = 1; $GameIdx <= 17; $GameIdx++) { /* instead "hardcoding each radio button name - just do it programmatically by concatenating / creating the name */ $frmGame = "Game" + $GameIdx; if ($frmGame) { /* U want to check if the length is 5 or 6 bytes because it could be "game1" or "game14" */ $Length = strlen($frmGame); if ($Length == 5) { $GetNumber = 1; } else { $GetNumber = 2; } $GameID = intval(substr($frmGame, $Length - $GetNumber, $GetNumber)); print "Game ---> $GameIdx - $frmGame - $GetNumber - $GameID <BR>"; if ($GameID == $GameIdx) { print "Yeah Match - $GameID = $GameIdx <BR>"; /* OK, here is where U want to do the actual insert */ } } /* $frmGame endif */ } ?> Thanks
